DOOR CONSTRUCTION.

Application led November 9, 1921.

To aZZ/ww/m, t may cow/cem:

Be it known that we, JOHN H. CRisT and Louis G. CRis'i, citizens of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania,

have invented certain vnew and useful. Improvements in DoorConstructions, of, which the following is a specification.

Our invention consists of an improvement in door construction, and is particularly adapted to the manufacture of doors or making water tight closure, as in the case of shower bath doors, or in any similar utilization, for the purpose of preventing notl only splashing of water, but passage between the door and the frame at any points.

In the application of the invention as herein illustrated and described; it is used in connection with the type of shower bath 2o known in the trade as stalls. In such construction, the shower` bath stall is of' comparatively small dimensions, usually -rectangular in form, with a depressed floor or receptor, having an entrance and exit opening through one of the surroundin walls, and usually provided with a, door sil either elevated above or on the, common level with the outer floor surface.

In the drawings, illustrating one` preferred embodiment of the invention as thus used V Fig. 1 is a view in outer elevation of th complete door; Fig. Q is a vertical sectional'view, artly broken away, on the line II-II of 1g. 1;

Fi 3 is a similar cross sectional view o the line III-III of Fig. 1;

Figs.l 4 and 5 are detail sectional views of the metal bar used for the side and top 40 of the door framing.

Referring to the drawings, the -shower bath stall 2 is positioned within the o uter surrounding wall portions, and provided with the depressed floor" or 'receptor 3, usually of porcelain, or other suitable material,

and having the usual drainoutlet, the stall having any standard or suitable water supply and shower bath equipment, as will be o readily understood.

stall, and suitably elevated above the receptor or bottom thereof, is the sill 4 which may be slightl inclined, as shown, or level, if preferred. he sill 4 is located between At the entrance and exit portion of the i Serial No. 513,895.

be understood as being applicable to any such standard form of framing, with. any suitable inish of various designwithin the section of the user.'

For the purpose of providing a mounting for the door itself, we use L-shaped strips of rolled brass or other Suitable metal having attaching base portions 7, and inwardly extendin right angled flanges 8. In the construction illustrated in the principal iigures of the drawings, a supplemental angle shaped member 9 is secured in the corner of the angle between base 7 and fla-nge 8, with a narrow intervening space 10, member 9 being brazed or otherwise secured, so as to hold it rigidly in relation to the flange 8.

. Inserted between member 9 and flange 8, 1n cavity 10, is a strip vof rubber tubing 11, the inner portion of which is tightly pressed together or tight insertion between'members 8and 9 in space 10 -for secure holding therein, leaving the outer portion of the rubber tubing of somewhat bulbous or protruding formation. Such strip extends entirely around the two vertical sides and the upper framing portion of the door cavity, in a se- `ries of'sections meeting at the corners and provides a sealing member for engagement against the adjacent face portion of the door framing.

In the modified construction of Fig. 5, I' al with showthe member 9 as formed inte the base member 7a and in fixed re ation to the flange 8, leaving the intervening space 10a in all respects similar to the construction above described, and adapted to the reception of the strip of rubber tubing.

The door shown in elevation in Fig. 1, is'of suitable dimensions to t neatly wit-hin the framing cavit but with a slight clearance between its ower bottom portion and sill 4. The door framing is preferably constructed of side members 12 and 13, a tog kmember 14, and a lower member 15, frame together in rectangular :form and provided with a glass pane 16, preferably v of plate 13, 14 and 15v are-preferably `of box form, as

shown, of suitable plate metal construction, with a wooden` or other filler -19, acting as a self-sustaining door frame between theV Strips 17 and 18, and embracing the inserted edges of the pane 16 are strips of 'rubber tubing 20, slitted along one side and tightly inserted', as shown, providing for a water sealingmounting of the pane itselfbetween the strips, and also providing ample cushioning resiliency for protection againstl shocks, etc. The use of tubing in this way ensures proper placing and continuous seallng at each side of the edges of the pane.

The door as thus constructed may be continuously tight, as shown, or, if referred, may have any suitable open gril work at the top for ventilation, as will be readily understood. The lower inner portion of theV base framing member 15 is provided with a downwardly extending resilient -sealing strip 21 of rubber tubing, tightly clasped between the metal box member 15 and an outer attached vretaining strip 22, of Z- shape, secured by base 23 against 'the inner face of the 'base member 15, similar to the mounting ofsealing strips 11.

A splash coping 24 secured at the upper inner edge of the base strip 15,. as at 25, extends inwardly and downwardly towards the receptor bottom, terminating a short distance above the level of the sill 4, so as to deflect water inwardly to the basey portion ofthe receptor. n

The door is mounted along one of its vertical edge portions to the adjacent side framingl member 7 by a continuous series of hinges v26 of the piano type, so as tonot only ensure ample support and good mounting of the door, but also providing for a continuous supplemental closure at the hinge side. The other edge portion of the door is provided both outsidev and inside with suitable knobs or handles27, for opening or closing from either side, together with any suitable spring or friction devices for holding the door in closed position.

As thus constructed and mounted, the door fits snugly within the framing menibers 7, and when closed, bears by the inner faces of its frame portions 12, 13 and 14 against the bulbous portion .of the several straight sections of rubber tubing 11, pressing them against the resisting Hanges 8 and elfect n ing a tight closure when the door is closed The strip 21 also bears by its bulbous'prostrip of metal havin message truding portion against the upper face of sill 4, thereby also effecting a similar sealing closure, the several strip members of rubber tubing meeting each other at the corners in a miter joint, and providing a practically continuous exible sealing 'member around all four sides. l

` The several metallic portions of the structure, both stationary framing and the movable door framing, and all of its metallic parts are preferably made of non-corrosive material, or are suitably plated, as by nickel plating, so as to render the structure impervious to the effects of moisture, and easily polished. The door as a whole is not only extremely efficient in performing its intended functions, in lthe particular manner of its mounting and location, but is also highly ornamental and provides a very efficient portion'of the equipment of the particular type of shower bath installation to which it is` adapted.

It willl be understood that the door and its. frame and the parts thereof may be made in various dimensions and designs as to particular formation of the framing members themselves, or other parts but all such changes are to be understood as within the province of the skilled mechanic or builder.

What we claim is:

1. ln a water tight doorconstruction, the combination with a rectangular framing providing a door opening, of a metallic frame member L-shaped in cross-section having a base secured against the opposite sides and top of the door opening framing and a flan-ge projecting at right angles from said base, a resilient sealing member secured against said flange, an inner supplemental holding flange engaging said sealing member, and a swinging door connected by hinges secured to the opposite edge portion of the base at one side of the opening adapted when closed to bear against the sealing 2. In combination with a swinging door,

a receiving frame formed of an L-shaped an attaching base and a main projecting ange, an inner supplemental ange parallel with said flange and spaced therefrom and extending partway of the width of said Hange, and a sealing strip of rubber tubing inserted tightly between said flanges and extending by its free bulbous portion outwardly Valong and against the main flange and providing a sealing and cushionin contact member for the door.

1n testimony whereof we hereunto alhx our signatures.
